【摘要】 根据东营凹陷西南部纯化油田辉绿岩岩体的岩性、电性及地震等特征,该岩体分带明显,可划分为中心相、边缘相、边外相,岩体电性特征分为渐变型、台阶式渐变型、上部跳跃渐变型、中部凹陷型等4种类型,岩体地震相可划分为破碎地震相、粘连地震相、串层位地震相、眼状地震相等4种类型。该火成岩主体与其边-外变质储集带是一个统一的复合体,对该岩体的储集能力进行了分析,提出边-外变质储集带是侵入岩中找油的新领域。图8参7更多还原

【Abstract】 According to the lithology, electricity and seismic facies of lava distributed in the southwest Chunhua Oilfield, the rock-body is well-regulated and divided into center facies, marginal facies and outside facies. The electricity characters of rock body are divided into four types as gradual change, step gradual change, top leaping gradual change and center depression type, respectively. The seismic facies are also divided into four types as cracked seismic facies, conglutinant seismic facies, multi-stratum seismic and eye-like seismic facies. The main lava body and metamorphic rock should be the new play domain in the intrusive lava.更多还原
